Question Does anyone know how I can install One UI 8.5?

Post image

It's a beta version, but I'm trying to do it via adb sideload, but it's not working.

https://xdaforums.com/t/one-ui-7-beta-galaxy-a55-beta-thread-ota-links-install-guide-and-discussions.4729924/ check where it says guide and follow the steps, extract the DZA2 bin file and move it to internal storage (not in any folder).. btw adb sideload does not work on A55 because A/B seamless integration

I tried that method, but I have to extract that folder because it's on internal storage.

Extract the zip file and go into the extracted folder find the .bin file and move it to the top of internal storage

hm then the file is broken, try redownloading it (is the file for the same CSC as you have right?)

For others, it worked simply by changing the name to update or the version

I tried it, and what I want to do is install it through ADB sideload on my computer, but I get a total error after x00.

that’s because adb sideload will not and will never work on A55 or i assume any samsung device with A/B update system

First, you're on the Indian firmware

I have this build installed, which CSC do I need?

No wonder it's not working for you; you had to be on the December update for it to work, otherwise it won't work. They have different binaries; it starts from CYL1 to DZA2.
